If you're worried about the PSU . . . don't. I have a 2500K @4.71, 5850, Xfi XtremeMusic, a SSD, a 1.5 Green Power, 2.0 Green Power, and two 750 GB Caviar Blue's, 2 case fans and a Cooler Master Hyper 212+ all running off a Antec TruPower New 650. No hiccups. If you can't find the Asus board anywher...
